Razor-Mouth is a great white shark that first appears in the Season 1 episode "Stuck on Sharks". She was chased by two orcas, (the only natural predator of great whites) but she managed to get away by diving deeper. She was captured by Chef Gourmand, but Martin and Chris managed to save her. She later gave birth to three pups, who she is the mother of, but left them since they had what it takes to survive on their own.
